ABSTRACT:
A valve is disclosed which controls flow of fluid through its body from inlet to outlet, and which has a co-operating valve seat and valve closure member. The closure member is actuated by an operating element which comprises an integral stem and diaphragm, the stem projecting from both faces of the diaphragm. One stem part is connected to the closure member and the other part is free and acts as the actuating member. The diaphragm is secured in and seals the aperture through which the stem projects from the valve body. Heat-sealing of the periphery of the diaphragm to the bounding wall of the aperture is disclosed, and the stem can be stiffened by a metal rod embedded therein. The diaphragm is distorted and acts as a pivot for the stem when the free part of the stem is displaced. The valve is disclosed as forming part of an air-gun and as part of a bath shower unit.
